This is the support bogie with a sort of anti derail on top that was introduced to reduce costs by dropping some wheels.
I understand the situation that the anti derail block should never be able to touch runway beam under acceptable user conditions.The only possibility must be that the crane has been used in violation of instructions.ie.Load on one end with other end outside runway beam so the whole download is resting on anti derail.
